In the use cases of partition and subpartition in super large tables, partition and subpartition are two common keywords in super large tables. They are mainly used for partitioning to improve data reading efficiency. (For more information about partition types and syntax, see the article on the Internet.) Today, we can see an application solution that combines range partitions with business processing. It

Three kinds of relationships between use cases : (1) extension (extends): use case B extends use case A, which indicates that use case b is an extension use case that may occur in a particular case. For example: Lao Wang i

In general, you can use is a and has a to determine which relationship to use. The generalization and extension relationships represent the is a relationship between use cases, and the relationship represents the has a relationship between use

very happy, here for the similarities and differences between Ajax and JSONP to do some additional explanation:1, Ajax and JSONP the two technologies in the invocation of the way "looks" very much like, the purpose is the same, is to request a URL, and then the server to return the data processed, so the jquery and ext and other frameworks have Jsonp as a form of Ajax encapsulation;2, but Ajax and JSONP are actually different things in nature.

, obviously, if your users don't mind that your program interface doesn't respond to user action, no problem! But what if you mind?At this point, open a local event loop, let it execute 100ms after its own exit, it seems very good.

request is successful. To execute a function when an error occurs, use $. ajax.Description: displays the return value of test. aspx (HTML or XML, depending on the returned value), and adds a set of request parameters. JQuery code:$. Get ("test. aspx", {name: "John", time: "2 "},Function (data ){Alert ("Data Loaded:" + data );});$.
